Hello everyone,
I am trying to solve a problem like \nabla(D\nabla T) +f =0 where D is a function of x and y, (x,y being the coordinate system) with some well defined boundary conditions (Dirichlet or Neuman). I want to have a simple FDM discretization like Gauss Seidel or SOR method, but since D is varying spatially I doubt that my simple scheme can work. Does anyone know any better solution? Thanks, |

I do not understand your question... GS, SOR are iterative algorithms for solving algebric linear systems, are not FDM discretization... In second order discretization you can proceed for example: [(D* dT/dx)|i+1/2-(D* dT/dx)|i-1/2]/dx |
